Garnett hurt in Boston’s 104-92 loss to Detroit -- The AP reports: Kevin Garnett left in the first quarter with a leg injury, and the Celtics looked ragged without him in a 104-92 loss to the Detroit Pistons on Wednesday night. Boston lost for only the second time in 17 games, but the Celtics are suddenly facing some adversity they hope isn’t too serious... Tracy McGrady—himself no stranger to leg problems—scored a season-high 21 points for the Pistons. He also played over 30 minutes for the first time since March... Tayshaun Prince added 18 points for Detroit. Paul Pierce scored 33 points for the Celtics, but he was fighting a losing battle on this night.
